DON (6-diazo-5-oxo-L-norleucine), a glutamine antagonist, has been subjected to limited clinical trials since 1957. Use of the drug in adults has been curtailed due to sparse reports of effectiveness as well as its dose-limiting toxicities, i.e., severe nausea, vomiting and mucositis. In earlier

The toxicity of the glutamine antagonist 6-diazo-5-oxo-L-norleucine (DON) administered as a 24 hour infusion has been evaluated. Studies of the clinical pharmacology of the drug have also been performed in 3 patients. The limiting toxicity of the drug was acute nausea, vomiting and diarrhea that was

We conducted a phase I study of 6-diazo-5-oxo-L-norleucine given iv on a twice weekly schedule. Twenty-six evaluable patients received 31 courses of the drug. Doses ranged from 100 to 500 mg/m2. Nausea with vomiting was the dose-limiting toxic effect, transient thrombocytopenia was seen frequently,

6-Diazo-5-oxo-L-norleucine (DON), an L-glutamine antagonist, was administered to 25 evaluable patients with refractory advanced solid tumors in a phase I trial. A total of 58 evaluable courses of five daily iv injections every 3-4 weeks were given, at doses ranging from 7.5 to 90 mg/m2/day. The

Ninety-eight patients with previously-treated advanced soft tissue sarcoma, bone sarcoma, or mesothelioma were randomly assigned to one of two intravenous single-agent treatment regimens, either 6-diazo-5-oxo-l-norleucine (DON; brief infusions of 50 mg/m2/day for 5 consecutive days every 4 weeks) or

The broadly active glutamine antagonist 6-diazo-5-oxo-L-norleucine (DON) has been studied for 60 years as a potential anticancer therapeutic. Clinical studies of DON in the 1950s using low daily doses suggested antitumor activity, but later phase I and II trials of DON given intermittently at high

Twenty-three patients with advanced colorectal carcinoma, previously treated with chemotherapy, were entered in a phase II trial of DON (6-Diazo-5-Oxo-L-Norleucine), an antagonist of L-glutamine. One of 14 adequately treated patients had a partial response of 6 weeks duration. The dose-limiting
